found only in the rocky mountains and their neighborhood. I first met 

 with this bird above the three forks of the Missouri and saw them on the 

 heights of the Rocky Mountains but never before had an opportunity of 

 examining them closely, the small corvus described at Fort Clatsop is a 

 different species, [ = Perisoreus] though until now I had taken it to be 

 the same, this is much larger and has a loud squawling note something like 

 the mewing of a cat." A good description follows. 



As Alexander Wilson described these birds from specimens brought 

 home by the expedition it follows that the locality where the specimens 

 were shot becomes the type locality not that at which the species were 

 first seen, as given in the A. O. U. Check-List. — Witmer Stone, Acad.

RECENT LITERATURE. 



Levick's 'Antarctic Penguins.' 1 — Since the return of the various 

 Antarctic expeditions of the last few years the general public, through 

 lectures, motion pictures and publications, has come to have a better 

 knowledge of the life history of Penguins, than most of the best informed 

 ornithologists possessed a decade ago. The life history of these curious 

 birds is well worthy of the attention it has received and cannot help but 

 fascinate all who are interested in the study of wild life. Dr. G. Murray 

 Levick who accompanied Capt. Scott on his ill-fated expedition has pre- 

 sented the story of the Penguins in a most attractive way in the little 

 volume before us, based on his experiences with the Adelie Penguins 

 (Pygoscelis adelia?) at Cape Adare. The book is well written, well printed 

 and illustrated by 74 admirable half-tones from photographs. 



What corresponds to the ' spring ' migration of the Penguins began on 

 October 13 when the first arrival from the north reached the breeding 

 ground, and in the course of a week thousands upon thousands of the 

 curious birds had landed and waddled across the ice and snow to the rookery 

 many of them ascending a thousand feet to the highest part of Cape 

 Adare. 



The Adelie Penguin builds a nest of pebbles upon which the two eggs are 

 laid and incubated alternately by the parent birds. Until this time neither 

 males or females leave the rookery and consequently get no food though 

 the males eat snow from adjacent drifts. The fasting period lasts 27 days 

 or more, and afterwards there is a continuous stream of dirty incubating
